NEWER PLIOCENE BEDS IN BRITAIN. 293 
because the specimen was not derived. He noticed that a species 
of Antelope, belonging to the genus Saga, already found in France 
and Belgium, occurred in Britain in Pleistocene times. Its remains 
were found a few years since, it was said, near Bedford. 
Mr. H. B. Woopwarp remarked on the valuable corroboration 
furnished by the specimen subsequently obtained by Dr. A. King 
from the same locality, and expressed his opinion that the Mam- 
malia found in the Norwich Crag belonged as much to the period as 
the Mollusca with which they are associated, the former being 
borne down by streams or tumbling over the chalk cliffs which in 
places bounded the Crag sea. 
The AvuTHor in reply said that he had not been able to examine 
the recent North-African forms so thoroughly as he could have 
wished: but none of the Dorcas-Gazelle skulls in the British Museum, 
or of those in the Royal College of Surgeons, were so like the fossil 
as was that of G. Bennettii: and the brain of an Egyptian Dorcas 
Gazelle in the latter collection also showed less resemblance to the 
fossil than did that of G. Bennett. He thought the fossil species 
eame nearer to G. Bennettw than to either form of the Dorcas 
Gazelle.
